l 'Specification of Letters Patent. Patnted Aug. 15, 1911. Applicationled April 11, 1910.

Serial No. 554,720.

To all 'whom it may concern.'

Be it known that I, GEORGE W. FLAD, a citizen of the United States,residing at St. Paul, in the county of Ramsey and State of Minnesota,have invented new and useful Improvements in Engine-Jacks, of which thefollowing is a specification.

My invention relates to improvements in engine jacks of the classadapted for supporting automobile engines and similar mechanisms whilein the shop during the process of overhauling and repair.

My object is to provide an adjustable support adapted to hold engines ofdifferent types and dimensions and present them to the mechanic in aposition to facilitate work thereon, and also to make easy changes inthe position of the engine without injury thereto.

In the drawings, Figure 1 is a plan of my improved jack; Fig. 2 is afront elevation; Fig. 3 is an end elevation, and Fig. 4 is an enlargeddetail partly in section on the line '.r-x of Fig. 1.

The device comprises end frames 2, connected by side braces 3, clamps 4,one on each of the end frames, an engine support composed of two rails5, each provided with a rigidly attached axle 6, the outer portion ofwhich forms a journal 7 The lower and stationary member of each clamp 4forms a bearing 8 for one of the journals 7. The bearings 8 are carriedby the end fram'es 2, and the caps 9, forming the second member of theclamp, are connected with said bearing by set screws 10. Thus thejournals 7 are supported in the bearings 8, and when the set screws 10are loose, the journals may be moved transversely toward or from eachother for the purpose of adjusting them to various sizes of engines ashereinafter described, and when so adjusted, the engine may be revolvedso as to present it in the most convenient position to the machinist whois working thereon. After being so placed, the set screws in the clamps4 are tightened and the engine may be held rigidly in one situationuntil it becomes desirable to alter its position, when by manipulatingthe screws it can be turned and again rigidly adjusted. The supports arepreferably made of angle iron, and both anges thereof are perforated atsuitable distances with bolt holes or slots 11 to receive the bolts bywhich the engine is held in place.

Engines of substantially all standard types are attached to theautomobile by means of bolts passing through anges provided in bracketson the engine frame and. through the sub-frame of the automobile. Someof these flanges project vertically from the brackets and othershorizontally according to the style of engine. It is by means of thesebrackets that the engine is secured to the supports 5 of my jack, bybolts clamped through the {ianges on the engine bracket and the holes 11in either the horizontal or vertical flange of the support 5. The use ofslotted holes 11 in both flanges of the rails 5 adapts the jack toreceive a considerable range of sizes and styles of engines, and bymerely drilling new holes in the rails 5, the device can be used on anyordinary engine.

The clamps 4 are tted with bushings 4a in the usual manner. On one ofsaid bushings is formed an annular iiange 12, adapted to fit in thecorrugations 13 on one of the axles. lVhen the flange 12 is adjusted inone of the corrugations 13, a stop is formed to prevent side play of thejournals in these bearings, while an engine clamped in the support isbeing turned. I thus guard against the possibility of one of thejournals slipping from its bearings to the injury of the engine. v

It is, of course, obvious that my device is adapted to holdtransmissions and other mechanisms as well as engines.

Having described my invention, what I claim as new and desire to protectby Letters Patent is:

1. An engine jack, comprising rigidly connected vertical end frames, aclamp upon each of said frames and a separable engine support providedwith axles at right angles thereto, said axles terminating in journalsadapted to be adjusted longitudinally and angularly, and to be held insaid clamps and said supports being perforated to receive bolts for thepurpose of clamping an engine thereon.

2. An engine jack comprising end frames, each supporting agrip bearing,an engine support having axles mounted in said bearings, which areadapted when loosely ad- I justed to form a journal and When tightlyname to this vspecification in the presence of ACopies of this vatentmay be obtained for adjusted to form a clamp for said axles', one tvvosubscribing Witnesses. of said bearinGs and journals having va rib andgroove enbgagement constituting a stop v(JVEORGFEA WV' FLAD" to preventhorizontal movement of the axles V\7itr1esse's:` i in the griprbearings.Y JOHN E.
